can be divided in 2 groups :
Nishkaam (without intention) :
Yagyas are very broad. For example, devotion or our regular
prayers, agriculture and education all these are one or another
kind of Yagyas. For example if you are a teacher, you give knowledge,
so it is called Gyan Yagya. The basic symptom is that these
Yagyas have no certain desires for doing this and become fruitful
after a long time in an uncertain manner which you can't identify.
For example if you give a donation, you get this money or perhaps
more back in shape of profit in your business or a discount
in a purchase. If you study, or if you teach, you get helped
by that knowledge in a certain situation. Only thing is that
you can't expect immediate or certain result by these Yagyas.
Sakaam (with intention) :
you have a problem and you wan help, or you have certain desire
and you want to fulfil that, than you do Yagyas for intentions
or Sakaam Yagya.
Yagyas too have 4 types :
Planetary Yagyas :
Yagya helps you minimizing evil influences of the planets to
survive in a period with un-favorable planets. However a planetary
Yagya doesn’t help for all puposes. For example, it will
minimize evil energy from the time the Yagya starts, but can’t
remove the influences those you already have collected in last
years and due to which many problems are being arose. In other
words, planetary Yagya helps you for prevention of negativity
from the time of start but are not meant for healing problems,
or to support for success or achievements. For these purposes
we need Specific or intentional Yagyas. Some people believe
that they can make planets happy, but we rely on scientific
Vedic theories in which noone is special for the planets. We
do Planetary Yagya not to make them happy but to apply a filter
for evil energy around us. Planets are too big for us to manipulate.
2. Yagya for Prevention :
Yagyas are to prevent any danger that you feel or see in coming
future or it is predicted by your astrologer. For example, you
have symptoms of severe diseases and you can think towards death,
you see some legal issue and you can see some punishment or
arrest in future, you are feeling or seeing some economic crisis
in future or your astrologer sees coming danger or problem in
your life. In all these situations we do Yagya for prevention.
These Yagyas first try to avoid this danger and if the danger
is driven by your strong bad karma which can't be totally averted,
then the Yagya softens the pain, minimizes the dangers and gives
you strength to tolerate and survive in the dangers. So you
are assured about your survival without having worse consequences.
3. Yagyas for Cure :
your whole life you have collected several bad things those
occur as problems and dangers in your life. For example you
collect evil energies of your negative planets, your bad deeds,
the curses of your family, gods and anyone whom you might have
reached pain. All these get collected in your life and become
fruitful without being minimized or destroyed. A Yagya for prevention
helps you that you shouldn't be attacked by those bad karma's
from the starting of Yagyas but what about those evil karma's
of your earnings in past? We use for this purpose - Yagya for
cure. For example, you have already a diseases or may be you
are being obstructed for being married or for getting child.
So these problems have already begun and we need to cure these
problems. In this situation we need Yagyas for cure.
4. Yagyas for Desires :
Yagyas are performed for fulfilling your desires. For example,
you want a higher post or higher income or you want to buy your
dream home. You do Yagya for help in fulfilling these desires.
For example, you want to buy a house and that costs $400,000
but you have only $250,000. Now you need to arrange the rest
$150,000 and for that you probably ask your friends or perhaps
you would take a loan. Exactly same, to achieve something you
need good karma and when you have less good karma, you can’t
achieve that. For example you have 60% good karma to achieve
a post or a property. Now you do Yagya to generate 40% more
karma so that you should be able to achieve that desire. But
desire and dram will not say that you can desire anything. For
example, if you are a minister and you want to be prime minister
then it is a reasonable or possible desire. But being just a
public if you desire to be a prime minister, then it is over
ambition and Yagya too will not help for this. You will say
now, every prime minister has been a public. It is true, but
then go step by step. Like do Yagya for being a minister of
low level, and when successful then do it for high level minister,
and then too successful then do it for being prime minister.
In this way you see Yagya can do all but with right application.
